IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 194,249, dated March 5, 1872.

Specification describing a new and useful Improvement in Lamps, invented by WILLIAM BRoWN, of Newburyport, in the county of Es sexr and State of Massachusetts.

Figure l is a detail vertical section of my improved lamp arranged as a chandelier, part being broken away, and indicating in dotted lines the changes necessary to ad apt it for use as a stInd or bracket lamp. Fig. 2 is a horizontal section ofthe saine, taken through the line .r x ot'Fig. l. Fig. 3 is a detail view of a stand i'or supporting the lamp.

Similar letters ot' reference indicate corresponding parts.

My invention has for its object to furnish an improved lamp which shall be simple in coilstruction, convenient in use, reliable in operation, and entirely safe from explosion; and it consists in the construction and combination ot' various parts, as hereinafter more fully de` scribed.

A is the reservoir in which the oil is placed, and which may be made otA glass or metal, or glass and metal, as may be desired. The reservoir is iilled through an openingin its bottoni, which openingis closed with a screw-cap, 13. lhe cap 15 is made with a hole thronghit, which is closed with a. valve, (l. The valve U is held to its seat by a coiled spring, D,one end ot' which is attached to the valve C, and its other end is attached to a loop, E, which is secured to the said cap B. Ihe stein F of the valve O passes out through an opening in the cap B, and has a bottom, knob, or foot formed upon its outer end, which rests upon the bottom of the fountain or receiver G, so that the weight of the reservoir bearing upon the said valve-stein may hold the valve C away from its seatand allow the oil to iiow out freely. To the outer side of the cap B, around the opening in said cap, is attached a wire-gauze or iinely-pertorated sheet-metal cap, H, which prevents the possibility of iia-ine entering the reservoir A. By this construction, should the lamp be overturned or dropped from the receiver Gr, the valve C will be closed by the sprin gD as soon as the valvesten1 F is released from the weight, so that not a drop of oil can escape, however much the reservoir may be rolled about. I is a ring-partition, placed in the bottom of the receiver G, made of finelyperforated sheet metal. The partition I thus forms a cavity to receive the valve-stem F, and the shoulders of said partition should be of such a height that, when the valve-stem F has been pushed inward a sufficient distance to open the valve C, the cap B or the bottom of the reservoir A may rest upon the said partition, as shown in Fig. l, and thus relieve the spring D from having to support the entire weight of the reservoir A and its contents. The partition I thus forms a ring-chamber around the outer part of the bottoni ofthe receiver G,which said chaniberis filled with line sand, J,.or other suitable material, through which the oil iilters as it passes to the burner or burners. K are pipes, leading from thereceiver G to the burners, and the inner ends of which are closed with a wire-gauze or tinelyperforated sheet-metal partition, L which prevents the sand J from esca-ping through the said pipes K, and at the saine time prevents the possibility ot iianie entering the receiver Gr, even should an explosion occur at the burners. To the outer ends ofthe pipes K are attached receptacles M, which receive the oil from the pipes K, and the wicks by which the oil iscon v eyed to the burners, which are screwed into the upper ends ot' the receptacle M in the saine lnanner as they are ordinarily screwed into a lamp-collar. In the case ot' a lampchandelier, the arms or frame N are attached to the receiver G, as shown in full linesin Fig. l. In the case ot' a bracket or stand lamp, lugs O are attached to the receiver (Jr and reservoir A to receive the pivot P, as shown in dotted lines in Fig. l, so that the lamp may be turned from side to side, to throw the light as may be required. The pivot Pina-y be secured to the wall permanently, or it may have a hole through its base to receive the standard Q of the stand, in which case it is secured in place by a set-screw, It, so that it may be turned from side to side, or moved up and down, as may be desired. S is the base or foot of the stand, which may have screw-holes formed in it, so that, by reversing theposition of the pivot P upon the standard Q,the base or foot Sinay be screwed to the ceiling, enabling the lamp to be used as a hanging lamp. T is a wire or arm, attached to the receiver G, and curving upward and outward over the burner, to support a heat and smoke protector, and which thus turns with the lamp so as to be always over the burner.

The pipes K may be made of an1 desired length, so that when the lamp is used on railroad cars the reservoir A and receiver Gr' may 'be placed at anr desired distance from the. burner, or even outside of the cars. The receiver G should be screwed into or otherwise detachably attached to the ringer base of the armsor frame N,sothatthe receiverandburners may be taken down when required for triniming the Wicks or for other purposes.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination 0f the stand P Q, It S,
